IMPROVED BOILER FO'MAKING MAPLE-SUGAR.

TO 'ALL WHOM IT MAY CNCERN:V

Be it known that I, GAIUS L. PARKER, of Coventryville, in thev county of Chenango, and lin the State of New York, have invented new and useful Improvements in Boilers for Making Maple-Sugar; and Ido hereby declare that the following is a full, clear, und exact description thereof, reference being had to the accompany. ing drawings, and thc letters of referencegmarked thereon.

In the annexed drawings, making a part of this specification- Figure 1 represents a perspective,

Figure 2 represents a -plan view, and

Figure 3 is an ve'nd'view of my evaporator or boiler for making maple-sugar.

A represents a metallic' plate, of suitable dimensions, bent in such manner and shape as to form an arch, the sides again bent upward, nearly parallel with the sides of the arch, and extending samewhat abovethe top of the said arch, in a. vertical position.

B represent end pieces, of a shape to correspond with the space betweenthe sides of the boiler and sidesv ofthe arch at its top, and which are fastened so as to makethe boiler water-tight.

At one endthere are holes, :c z, at the bottom of the boiler-,which is near the ground 'or base upon which it is designed to rest, for the purpose of aiording a convenient 'device for letting oi water whenever it-maybe necessary to empty the boiler, or to 'draw o sirup that may bemade therein. v It'will be seen that by this device there is a narrow space between the side ofthe boiler and the side of the arch which forms a part of the boiler.

This boiler may be placed on the ground where it may be desired to use it, or upon any suitablebase, and the tire huilt beneath the arch thereof, both ends of which are ope'n, and the sides and bottom both derive heat from the lire, and as the article or material to be heated is, brought in contact with the sides aswell as bottom of the heated surface, it follows that nearly or quite double the heat' of the same tire is made available to what` would be secured by the use of an ordinary boiler.

This boiler is, for convenience, provided with handles, C C, at each end. Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is The cast-iron heads B B, with narrow flanges extending outwards, so that the sheet metahA, may be bent or stamped, to conform to the shape of the heads, and thereto be riveted tothe flanges, all constructed and used as specied.

l In testimony that I claim the foregoing, I have hereunto set my hand, this 21st day of December, 1867.
